Extramedullary hematopoiesis in the liver in sudden infant death syndrome.

This study was undertaken to confirm or refute the findings of Naeye with regard to the pathologic continuation of extramedullary hematopoiesis in the livers of infants who die of the sudden infant death syndrome (SIDS). In general, our findings confirm his; however, although the data for SIDS do differ from those of controls, the differences are not statistically significant. Nevertheless, these results would seem to indicate the need for further investigation of the possibility of hypoxemia and/or anemia in affected infants.
